I'm currently checking the VI API to see where to gather the information for dump-xml, but it seems one needs to read most of it from the .vmx file of a virtual machine located on the host. Luckily all files of a virtual machine are readable via HTTP: http://example-esx-host.com/folder/... So the .vmx file is easily accessible using libcurl.
Luckily (again) there is some unofficial documentation about the VMX format available: http://www.sanbarrow.com/vmx.html
Yeah the VMX file format is quite straightforward to read / write. We already do a similar thing for Xen's configs in /etc/xen - the raw config file parsing code for that is in src/conf.c, and the code to convert XML <-> XM Config is in src/xm_internal.c
Within the next few days I'll post a proposal on how to map a .vmx file into the libvirt xml representation.
For create-xml the ESX driver would need to write a .vmx file to the ESX host, because the .vmx file is essential to create a virtual machine. Luckily (once again) the ESX host allows putting files to http://example-esx-host.com/folder/... via HTTP.
Again, sounds pretty straightforward & a reasonable way to go.
